Fourth & Fifth Z-drive Towboat from Master Marine

In August and September respectively, Marquette Transportation Co. took delivery of the fourth and fifth 2,000-hp Z-drive towboat from Master Marine, Inc., Bayou La Batre, Ala. The 78 x 34 x11-ft.

Master Marine is continuing to build Z-Drive towboats, with more underway for Marquette, said the yard’s president Randy Orr.

The package gives the boat a running speed of 10 knots with a loaded draft of 8 ft. For ship’s service power the towboat is outfitted with a pair of Kennedy Engine John Deere 4045AFM85 Tier 3 generator drive engines each driving an 80-kW Marathon Mariner generators. Cooling for all engines and z drives was provided by Eastpark Radiator Duraweld coolers. Doors and windows were provided by Dales Welding & Fabrication, LLC. Rubber bumper systems were provided by Schuyler Companies. The electronics was supplied by New World Electronics and the Rio Marine supplied the alarms and monitoring systems.
